Ratios Should Have Clear Numerators And Denominators

The most interesting metrics are ratios of underlying measures. Oftentimes, interesting filtering or other data choices are hidden in the precise definitions of the numerator and denominator. For example, which of the following does “Queries / User” actually mean?

  • Queries / Users with a Query
  • Queries / Users who visited Google today
  • Queries / Users with an active account (yes, I would have to define active)
  • Being really clear here can avoid confusion for yourself and others.
